TUBING-RING.

SPECIFICATION forming part of Letters Patent No. 780,861, dated. January24, 1905. Application filed May 28, 1904. Serial No. 210,293.

To all whom t may concern'.-

Be it known that I, EDMIRE D. BUZARD, a citizen of the United States,residing at Pollock, in the county of Clarion and State of Pennsylvania,have invented new and luseful Improvements in Tu loing-Rings, of whichthe following is a specification.

My invention relates to new and useful improvements intubing-rings suchas employed for carrying the weight of tubing used in oilwells; and its.object is to provide a ring `formed of sections which can be readilyresections are oppositely disposed and placed one upon the other apractically solid ring having a central opening therein is produced.These sections are prevented from moving independently of each other andwilllirmly support the tubing. i

The inventionalso consists in the further novel construction andcombination of'parts hereinafter more fully described and claimed, andillustrated in the accompanying drawings, showing the preferred form ofmy invention, and in which- Figure l is a perspective View of acasinghead such as used in oil-wells and showing my improvedtubing-rings in position lunder the couplings of tubing. Fig. 2 is anenlarged section through one ofthe ringsand showing in dotted lines atube and its coupling in position therein, and Fig. 3 is a perspectiveview.

showing the two parts of the ring detached. Referring to the figures bynumerals of referenee,l and 2 are sections which when assembled form thering which constitutes my invention. Section l has a slot 3 extendingthereinto from'its periphery, and atthe'inner end of this slot is formeda projection 4:, the opposite ends of which aline with the periphery ofthe section 1 and the end wall of the slot 3, respectively. The sides ofthis projection are parallel, andthe distance between'the sides is equalto the width of the slot 3. Oppositely-disposed wedge-shaped recesses 5are formed within the section 1 at points equidistant from projection 4.The section 2 of the ring has a slot 6 extending thereinto from itsperiphery, which is equal in length, width,

connecting sections of tubing. After the tubing has been lowered todesired points within the casing of the well the same is adapted tobeheld by placing a ring therearound and below one of the couplings, soas to cause the casing-head to receive the entire weight of the tubing.

.By employing my improved tubing-ring said ring can be readily placed inposition by firstl sliding the section 1 with its flat face downwarduntil the tubing contacts with the inner end of the slot 3. The section2 of the ring is then placed over the section land slid longitudinallythereon. Projection 7 will move into slot 3 and projection 4 will bereceived by slot 6. When projections 8 arrive above the recesses 5, theywill drop thereinto, and the two parts of the ring will thus be securelyinterlocked, and the coupling to the tubing can be placed thereon andthe entire tubing firmly supported. Should it be necessary to remove thering for any purpose,

this can be done without breaking it, as it is i merely necessary topartly raise the tubing and to then lift the upper section 2 of the ringand slide it laterally from engagement with the other section. j

In the foregoing description I have shown .the preferred form of myinvention; but I do not limit myself thereto, as I am aware that IOOmodifications may be made therein without departing from the s'pirit orsacrificing any of the advantages thereof, and I therefore reserve theright to make such changes as fairly fall within the scope of myinvention.

Having thus fully described the invention, what is claimed as new is- 1.A tubing-ring comprising sections having slots extending thereinto fromthe peripheries thereof, a projection upon each section and between theend of the slot and the periphery of the sections, `andoppositely-disposed projections on one of the sections tapered fromtheir outer to their inner ends and adapted to lit within similarrecesses in the other section.

2. A tubing-ring comprising a section having a slot extending thereinto,and opposite] ydisposed recesses in one face and tapered from theirouter to their inner ends, and a projection upon said face and betweenthe end of the slot and the periphery of the section, and asecondsection having a slot extending thereinto from its periphery, the slotsof the two sections being similar, oppositely-disposed projections uponone face of said second scction and tapered from their outer to theirinner ends, and a projection upon said face and interposed between theend of the slot and the periphery of the section.

3. The combination with the head of a wellcasing, of a tubingringarranged thereon comprising opposite]y-disposed slotted sections, aprojection upon cach section and between the end of the slot and theedge of the section, each projection being adapted to lit within theslot of the other section to forni a central opening, and projectionsupon theinner face of one section and tapered fro'n their outer endstoward the center of the section and adapted to lit within similarrecesses in the inner faces of the other section.

In testimony whereof 1 aiix my signature in presence of two witnesses.
